Problem with multihomed pc and vpn - local network access

I work for a law firm and we are starting to routinely set up shop in hotels for trials. What I thought I could do was create a mini LAN in the hotel conference room consisting of a switch with several laptops, a server, and a local network printer connected and use the laptop's dual network cards to connect to the Internet and the local network at the same time.

I have the local mini LAN configured with 10.10.10.x,, no gateway addressing which the server acts as DHCP for this range. I plug the wire into the switch giving the laptop's NIC a 10.10.10.x address. Then I use the laptops wireless NIC to get on the hotels Internet connection.

All works well. I can access both the Internet and print until I connect to VPN. Once connected, we use Cisco's web based AnyConnect, the VPN gets 192.168.200.x,, addressing but I am unable to connect to my 10.10.10.x LAN at all. I can even ping the printer. I am assume that traffic is trying to go through my VPN and finds a dead end. VPN works great. I can access my corp LAN fine, ping servers, etc...

Surely I'm just missing some sort of routing here. Is there anything I can do?

It sounds like the VPN client software is configured to send ALL data through the VPN tunnel. You maybe need to disable that feature.

That just may be the case. I looked at the vpn config on the ASA and I do have it to tunnel all networks. Seems as if I need to exclude the 10.10.10.x range but I will need someone more Cisco fluent do do that. Thanks

No, you don’t need to exclude 10.10.10.x range

The settings you need to look for are split-tunnelling and split-dns. They need to be enabled on Cisco ASA.

You can find the appropriate configuration through ASDM but in CLI it will be something like:

access-list LOCAL_splitTunnelACL standard permit 
group-policy SSL_VPN_Policy attributes
   split-tunnel-policy tunnelspecified
   split-tunnel-network-list value LOCAL_splitTunnelACL
   split-dns value your.local.domain

Open in new window

I hope this helps
